As shown in FIGS. 1 through 4, the variable speed training apparatus A1 of a continuous horizontal mechanism according to a first embodiment of the present invention comprises a frame 1, first and second rotation casings 3 a and 3 b which are opposed to each other and are installed in both sides of the body frame 1 at slanted angles, and a driving force transfer unit which connect the first and second rotation casings 3 a and 3 b.

As shown in FIG. 2, the driving force transfer unit comprises a horizontal shaft 100 horizontally installed in an inner side of the body frame 1, a crank shaft 2 which is installed in the center of the body frame 1, with its end being connected with the horizontal shaft 100 through a connection member 9, a fixing gear 6 which is fixed in the crank shaft 2, a pedal shaft gear 7 connected with the pedals 4 a and 4 b, and a belt member 8 which connects the fixing gear 6 and the pedal shaft gear 7.

The connection member 9 is provided for transferring a rotational force of the horizontal shaft 100 to the crank shaft 2 and is preferably made of a universal joint. Other types of connection units might be used.

As shown in FIG. 3, a tensional force adjusting unit 12 is installed in the interiors of the first and second rotation casings 3 a and 3 b for controlling a rotational speed by means of a frictional contact with the belt member 8.

The tensional force adjusting unit 12 comprises an idle roller 10 contacting with the belt member 8, a bracket 110 for axially fixing the idle roller 10, an adjusting bolt 120 integrally formed in an end of the bracket 110, and a spring 11 disposed on an outer side of the adjusting bolt 120.

The operation of the first embodiment A1 of the present invention will be described.

When a user steps on the pedals 4 a and rotates the same with a certain force, the first rotation casing 3 a rotates, and the left pedal shaft gear 7, the belt member 8 and the fixing gear 6 rotate, and the left crank shaft 2 rotates. So, the horizontal shaft 100 connected to a lower end of the left crank shaft 2 rotates.

As the right crank shaft 2 rotates, the second rotation casing 3 b and the right pedal 4 b rotate.

Here, the left and right pedals 4 a and 4 b maintain a horizontal state all the time.

The tensional force adjusting unit 12 might be adjusted so as to double an exercise effect by increasing an exercise load to the legs.

When the adjusting bolt 120 is tightened, the spring 11 is compressed, and the idle roller 10 closely contacts with the belt member 8, so an exercise load might be increased.

So as to decrease the exercise load, it is needed to loosen the adjusting bolt 120.

FIG. 5 is a cross sectional view illustrating a variable speed training apparatus of a continuous horizontal mechanism according to a second embodiment of the present invention.

As shown in FIG. 5, the variable speed training apparatus A2 of a continuous horizontal mechanism according to a second embodiment of the present invention comprises a body frame 1, first and second rotation casings 3 a and 3 b which are opposed to each other and are installed in both sides of the body frame 1 at a slanted angle and are equipped with pedals 4 a and 4 b, and a driving force transfer unit which rotatably connects the first and second rotation casings 3 a and 3 b.

The driving force transfer unit comprises first and second crank shafts 21 and 22 of which ends are eccentrically installed in the first and second rotation casings 3 a and 3 b, and the other ends are equipped with a bevel gear 200 a for engagement, fixing gears 6 a and 6 b which are axially installed in the first and second crank shafts 21 and 22 and are provided in the first and second rotation casings 3 a and 3 b, a pedal shaft gear 7 a connected to the pedals 4 a and 4 b, and a plurality of driven gears 80 which connect the fixing gears 6 a and 6 b and the pedal shaft gear 7 a.

The first crank shaft 21 is further equipped with the tensional force adjusting unit 12 a.

The tensional force adjusting unit 12 a might be installed in the second crank shaft 22, and might be installed in both the first and second crank shafts 21 and 22.

The tensional force adjusting unit 12 a includes an adjusting bolt 120 a thread-engaged to the body frame 1, and a disk 123 a which is formed in a rear end of the adjusting bolt 120 a and is closely contacted with the first crank shaft 21.

The disk 123 a is formed in a semicircular shape while closely contacting with the outer surfaces of the first and second crank shafts 21 and 22.

The operation of the second embodiment of the present invention will be described.

When the user steps on the pedals 4 a and 4 b and rotates the same for exercise.

When the user rotates the left pedal 4 b by applying a load to the same, the first rotation casing 3 a rotates, and the left pedal shaft gear 7 a, the driven gear 80 and the fixing gear 6 a rotate. The first crank shaft 21 of the left side is driven, and the second crank shaft 22 connected with the lower side of the first crank shaft 21 and the bevel gear 200 a rotate.

As the second crank shaft 22 rotates, the second rotation casing 3 b and the right pedal 4 b rotate.

Here, the left and right pedals 4 a and 4 b are in horizontal states all the time.

The tensional force adjusting unit 12 a is driven so as to double the exercise effect by increasing a load applied to the legs.

When the adjusting bolt 120 a is tightened, the disk 123 a friction-contacts with the first crank shaft 21, and the rotation is broke, so a lot of force is needed for rotation.

So as to decrease the load, the adjusting bolt 120 a is loosened.

FIG. 6 is a cross sectional view illustrating a variable speed training apparatus of a continuous horizontal mechanism according to a third embodiment of the present invention.

As shown in FIG. 6, the variable speed training apparatus A3 of a continuous horizontal mechanism according to a third embodiment of the present invention comprises a body frame 1, first and second rotation casings 3 a and 3 b which are opposed to each other and installed in both sides of the body frame 1 at slanted angles and include pedals 4 a and 4 b, and a driving force transfer unit for connecting the first and second rotation casings 3 a and 3 b and rotating the same.

The driving force transfer unit comprises a horizontal shaft 100 b which is horizontally installed in an inner side of the body frame 1, crank shafts 21 and 22 which are installed in the inner centers of the first and second rotation casings 3 a and 3 b with their ends being connected to the horizontal shaft 100 b through the connection member 9 b, a fixing gear 66 b which is axially installed in the crank shafts 21 and 22, a pedal shaft gear 7 b connected to the pedals 4 a and 4 b, a plurality of driven gears 80 b which connect the fixing gear 66 b and the pedal shaft gear 7 b, and a motor apparatus M connected to the horizontal shaft 100 b.

The connection member 9 b is a universal joint.

A tensional force adjusting unit 12 b is further installed in the interior of the first and second rotation casings 3 a and 3 b so as to adjust the rotation speed by means of a friction contact with the horizontal shaft 100 b.

Here, the tensional force adjusting unit 12 b includes an adjusting bolt 120 b thread-engaged to the body frame 1, and a disk 123 b which is formed in a rear end of the adjusting bolt 120 b and closely contacts with the horizontal shaft 100 b.

A control unit is further provided for selecting a manual mode and an automatic mode by controlling the on and off of the motor apparatus M.

The motor apparatus M comprises a driving motor M1, a decelerator MS connected to the driving motor M1, a driving pulley M2 connected to the decelerator MS, a driven pulley M4 axially engaged to the horizontal shaft 100 b, a timing belt M3 which connects the driving pulley M2 and the driven pulley M4, and an electronic clutch M6 which engages or disengages the connection between the decelerator MS and the driving pulley M2.

The electronic clutch M6 is a known apparatus for switching the on and off of the driving force transfer, its description will be omitted.

The operation of the third embodiment of the present invention will be described.

The control unit is set in a manual mode, and the user steps on the pedals 4 a and 4 b, and rotates the same for exercise.

When the user applies loads to the left pedal 4 a, the first rotation casing 3 a rotates, and the left pedal shaft gear 7 b, the driven gear 80 b and the fixing gear 66 b rotate, and the left crank shaft 22 rotates, and the horizontal shaft 100 b connected to a lower side of the left crank shaft 22 rotates.

So, as the right crank shaft 222 rotates, the second rotation casing 3 b and the right pedal 4 b rotate as well.

The left and right pedals 4 a and 4 b are in horizontals states all the time.

So as to double an exercise effect by increasing loads to the legs, it is needed to adjust the tensional force adjusting unit 12 b.

When the adjusting bolt 120 b is tightened, the disk 123 friction-contacts with the horizontal shaft 100 b, so the rotation is broke, and more load is needed for rotation.

So as to decrease the load, it is needed to loosen the adjusting bolt 120 b.

The automatic mode is selected by operating the control unit, and the motor apparatus M is turned on, and the driving motor M1 rotates.

When the electronic clutch M6 is turned on, the rotational force of the driving motor M1 rotates the driving pulley M2 and the timing belt M3 through the decelerator M5, and the driven pulley M4 and the horizontal shaft 100 b rotate.

When the electronic clutch M6 is turned off, since the rotational force of the driving motor M1 is not applied to the driving pulley M2, the transfer of the rotational force to the horizontal shaft 100 b is stopped.

The modified embodiment of the present invention will be described with reference to FIG. 7.

As shown in FIG. 7, a base 150 is installed in one side of the body frame 1, and a handle 160 is installed on an upper side of the base 150, and a cradle 170 is installed in the other side of the body frame 1.

An elastic unit 180 is installed in a lower side of the base 150, so an up and down twist motion can be obtained.

The elastic unit 180 includes a coil spring which connects the body frame 1 and the lower side of the base 150.

So, the user pedals the pedals 4 a and 4 b while holding the handle 160, and the user can perform a twisting motion using the handle while pedaling, so the exercise effect can be doubled.

INDUSTRIAL APPLICABILITY

According to the present invention, the crank pedals have the same inclinations, so it is possible to double the exercise effect during the pedaling of the pedals, and a waterproof function is provided, so it can be used in an outdoor. A saddle, a handle, various measurement units, and various exercise mechanism apparatuses can be combined and used.
